Application filed October 3l, 1905. Serial No. 286,287.

To au whom it may concern:

Be it known that l, CALVIN P. HARMrsoN, a citizen of the United States,residing at, Rice Lake, in the county of Barron and State of Wisconsin,have invented new and useful Improvements in Milk-Cans, of which thefollowing is a specification.

My invention pertains to milk cans, more particularly milk-cans havingVentilating-openings in their necks controlled by their caps and itcontemplates the provision of such a can having a cap constructed with aview of facilitating the passage of warm moisture-laden air to theVentilating-openings and preventing the collection of sweat or moisturein the upper portion of the can.

With the foregoing in mind the invention will be fully understood fromthe following descripton and claim when the same are considered inconnection with the accompanying drawings, forming part of thisspecification, in which- Figure 1 is a diametrical section of themilk-can constituting the present and preferred embodiment of myinvention, the

same being shown with the openings in its cap registered with theopenings in its neck. Fig. 2 is a horizontal section taken in the planeindicated by the line 2 2 of Fig. l looking upwardly and illustratingthe top of the cap in inverted plan.

Similar letters designate corresponding parts in both views of thedrawings, referring to which- A is the body of my novel milk-can, towhich is fixed the neck B, having the usual flange a at its upper end.The said neck B is peculiar in that it is provided adjacent to theflange a and at diametrically opposite points with openings l), whichare designed to permit warm and moisture-laden air to pass from the canand fresh cool air to enter the same. The said openings b, which may becircular, rectangular, or of any other suitable shape, are covered bywire-gauze or other suitable reticulated material, as indicated by c,this in order to prevent rain, bugs, and dirt from gaining access to theinterior of the can.

C is the removable cap of the can. This cap comprises a top d, having aflange e adapted to it snugly over the flange o after the manner shownin Fig. l, a circular flange f, fixed to and depending from the top d,so as to closely occupy the neck B, and having diametrically oppositeapertures g, adapted to be registered with the apertures b in said neck,as shown in Fig. 1, and a handle h, which is preferably arranged invertical alinement with the apertures g, so as to enable the user of thecan to readily determine when said apertures are registered with theapertures 0.

By virtue of the construction thus far described it will be apparentthat when the cap C is arranged, as shown in Fig. l, relative to theneck B warm and moisture-laden air is permitted to pass from theinterior of the can and fresh cool air is permitted to freely enter thecan. It will also be apparent that when the cap C is turned so as to setthe handle h at an angle to a line extending through the op enings b andc the openings b will be closed by the depending iiange j of the cap.

In order to enable the top d of the cap C to facilitate the passage ofwarm and moistureladen air given off by the milk to the registeredopenings g and b, I make the said top d as illustrated-that is to say,with a central depending bulge m and an annular channel n, roundedupward in cross-section, surrounding the said bulge. This formation ofthe top d is materially advantageous, for the reason that the bulge mand channel n will guide or deflect the air in the can toward theregistered openin s g and l), and thereby facilitate the escape of suchair and lessen the liability of moisture given off by the milk settlingon the under side of the top. It will also be apparent that the top d,formed as stated, affords no corners in which dirt can gather and thatit is adapted to be quickly and thoroughly cleaned with but a minimumamount of effort.

Notwithstanding the practical advantages which I have ascribed to thenovel cap C, it will be noted that the same is but little, if any, moreexpensive than the ordinary cap.

Having described my invention, what I upward in cross-section and alsohaving a i In testimony whereof I have hereunto set central dependingbulge m which merges at my hand in presence of two subscribing wititsupper edge into said iange n and 1n oomnesses.

bination with the same serves to guide or del ect the air in the cantoward the openings as Well as to prevent the collection of dirt in thecap.
